What is in this leaflet
Please read this leaflet carefully before you start using ARZERRA.
This leaflet answers some common questions about ARZERRA (ofatumumab). It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking ARZERRA against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
What ARZERRA is used for
ARZERRA contains ofatumumab, which belongs to a group of medicines called monoclonal antibodies.
ARZERRA is used to treat chronic lymphocytic leukaemia (CLL) . CLL is a cancer of the blood which affects the lymphocytes (a type of white blood cell). The lymphocytes multiply too quickly and live too long, so there are too many of them circulating in your blood. The disease can also affect other organs in your body. The antibody in ARZERRA recognises a substance on the surface of lymphocytes and causes the lymphocyte to die.
Your doctor may have prescribed ARZERRA for another reason.
This medicine is available only with a doctor’s prescription.
ARZERRA is not addictive.
Before you are given Arzerra
When you must not receive ARZERRA
You must not receive ARZERRA if:
- you have ever had a severe allergic (hypersensitive) reaction to ARZERRA (ofatumumab). Check with your doctor if you think this may apply to you.
- you have ever had an allergic reaction to any of the ingredients listed toward the end of this leaflet. (See “Ingredients”).
Some of the symptoms of an allergic reaction may include:
- shortness of breath
- wheezing or difficulty breathing
- swelling of the face, lips, tongue or other parts of the body
- rash, itching or hives on the skin
ARZERRA must not be used after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.
If it has expired or is damaged, return it to your pharmacist for disposal.
If you are not sure whether you should start taking this medicine, talk to your doctor.
Tell your doctor if:
Before you are given ARZERRA your doctor needs to know:
- if you have had heart problems
- if you have lung disease
- if you have had hepatitis B (a liver disease). ARZERRA could cause your hepatitis B to become active again. Your doctor may treat you with a suitable anti-viral medicine to help prevent this.
Check with your doctor if you think any of these may apply to you. You may need extra check -ups while you are being treated with ARZERRA.
Vaccination and ARZERRA
If you are having any vaccinations tell your doctor, or the person giving you the vaccine, that you are being treated with ARZERRA. Your response to the vaccine may be weakened.
Medicines of this type (monoclonal antibodies) are given into a vein (intravenously) as an infusion (a drip) over several hours. They can cause infusion reactions (side effects) when they are injected into the body. You will be given medicines such as anti-histamines, steroids or pain relievers to help reduce any reaction (see also ‘Side effects’).
If you think you have had an infusion reaction before, tell your doctor before you are given ARZERRA.
Progressive multifocal leukoencephalopathy (PML)
Medicines like ARZERRA may cause a serious and life threatening brain condition called progressive multifocal leukoencephalopathy (PML).
Tell your doctor immediately if you have memory loss, trouble thinking, difficulty with walking or loss of vision. If you had these symptoms prior to treatment with ARZERRA, tell your doctor immediately about any changes in these symptoms.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, have taken any recently, or if you start new ones. This includes herbal medicines and other medicines you’ve bought without a prescription.
Pregnancy and breast-feeding
Tell your doctor if you are pregnant or think you could be, before you are given ARZERRA.
There is no information about the safety of ARZERRA in pregnant women.
Use a reliable method of contraception to prevent pregnancy while you’re being treated with ARZERRA, and for twelve months after your last treatment.
Breast-feeding is not recommended during treatment with ARZERRA, because it is not known whether it passes into human milk.
Driving and using machines
ARZERRA is unlikely to affect your ability to drive or use machines.
ARZERRA contains sodium
ARZERRA contains 34.8 mg sodium in each 300 mg dose and 232 mg sodium in each 2000 mg dose. You need to take this into account if you are on a controlled sodium diet.
How do I use ARZERRA?
If you have any questions on the use of this product, ask the doctor who is giving ARZERRA to you.
How much to take
The usual dose for the first infusion is 300 mg. This dose will usually be increased to 1000 mg or 2000 mg for the remaining infusions.
How it is given
ARZERRA is given into a vein (intravenously) as an infusion (a drip) over several hours.
If you have not been previously treated for CLL you will usually have a maximum of 13 infusions. You will be given an infusion followed by a second infusion 8 days later. The remaining infusions will then be given once a month for up to 11 months.
If you have been previously treated for CLL, you will usually have a course of 12 infusions. You will be given an infusion once a week for eight weeks. This is followed by a four- to five-week gap. The remaining infusions will be given once a month for four months.
Before each infusion of ARZERRA, you will be given medicines which help to reduce any infusion reactions. These may include anti-histamines, steroids and pain relievers. You will be checked closely and if you do have any reactions these will be treated.
Check with your doctor as soon as possible if you think you are experiencing any side effects or allergic reactions due to receiving ARZERRA, even if the problem is not listed below.
